Abstract

Disclosed is high elasticity wave-absorbing anticorrosion nanometer coating with the weight ratio composition of 1-5% nanometer titanium alloy, 1-10% carbon fiber, 1-10% copper powder, 13-25% T-ZnO, 15-30% magneto plumbite type ferrite and 25-68% epoxy modified acrylic acid elastic resin; the radius of nanometer titanium alloy is 20- 50nm; the radius of carbon fiber is 20-30nm and the length of carbon fiber is 100-500nm; the radius of the particle of copper powder is 20-30nm; the radius of the particle of T-ZnO is 40-70nm; the radius of magneto plumbite type ferrite is 20-100nm and the lengthis 100-300nm; the Rho of epoxy modified acrylic acid elastic resin is equal to 1.1-1.2. The high elasticity wave-absorbing anticorrosion nanometer coating has super strong anticorrosion property and avoids the device from corrosion when the device operates under badly corrosive environment for long time; the anticorrosion nanometer coating is bonded firmly with the substrate and has the advantages of high elasticity and good wave-absorbing performance.

Description

technical field [0001] The invention relates to coatings, in particular to a high-elastic composite coating containing nano particles with both heavy anti-corrosion and wave-absorbing properties. Background technique [0002] The current heavy-duty anti-corrosion materials mainly include anti-rust pigments, stainless steel flakes, glass flakes, and relatively negative potential metal powders, etc., but the anti-corrosion effect is not ideal and cannot fully meet the needs. Existing wave-absorbing coatings include resistance type, dielectric type and magnetic medium type, and nano wave-absorbing coatings have also appeared. The base material is not firmly bonded, easy to crack and peel off, and the anti-corrosion effect is not good. Contents of the invention [0003] The object of the present invention is to propose a high-elastic microwave-absorbing heavy-duty anti-corrosion nano-coating, which uses titanium alloy nano-powder prepared from titanium, which is known as the ...
